It's a Voice over Internet (VoIP) carrier. A reverse lookup (411.com) says it's a MCI Worldcom Land Line I've had telemarketers and one of my vendors come in with that number. When a VoIP call is placed it goes over the Internet to the closest Bell switch where it is converted from VoIP to Land Line. Many calling cards as well as telemarketers use VoIP. I've had about 50 calls from this number from 8/20/07 to today with 3 different caller id names O, MIAMI FL, and FLORIDA

This number keeps calling and they dont say a word. Who is this? It's annoying. STOP

Calls me repeatedly. No idea what they want.

I dont want to give money to your jerk charity! All I want is a reasonably peaceful sunday evening. Thanks!

I think this is actually the government calling but they dont seem to be able to leave a message. So weird.

Called me today at about seven PM. No message left by these callers. Somehow they got my cell number. How?!!?!

I dont want to give money to your heavy breathing charity! All I want is a reasonably peaceful sunday evening. Thanks!

These male callers call me again and again. Never say anything. Never a message. loudmouth!

These male callers ask for me to return the call, but I don't plan to bother. What's the point.

These people who seem friendly call me again and again. Never say anything. Never a message. ridiculous!

Called me today at about four PM. No message left by these people who seem friendly. Somehow they got my cell number. How?!!?!

I said I dont know the person she wants. She yells at me that I should because I sound like her. Whatever.

This number calls me 3 days a week, at least 3 times every day.

They call me 6 times a week and ask me if I would be interested in some sort of weird credit card offer. I say no, then the next week its the exact same thing. Again and again.

This number doesnt show up anywhere else on the web. Thank you guys for having a listing for it.
